Servicio de Correo's role as an MX provider for smaller-business and long-tail domains means the inbound mail it receives is predominantly from senders targeting those recipient profiles, often including marketing-platform operators. Its filtering policies and reputation models are likely calibrated to that sender ecosystem rather than to patterns observed at tier-one providers; testing against it therefore provides insight into deliverability behaviour for campaigns targeting SMB and long-tail audiences rather than large consumer or enterprise segments.
